B55 AMG? Mercedes swaps an M273 5.5 liter V8 into the B-class

This is just a prototype, so don't get too excited. A dozen Mercedes apprentice engineers from the Rastatt facility decided to swap the big V8 into the B-class for fun. They started with a B200 CDI and took a naturally aspirated 5.5 liter V8 from the 550 models and swapped it in along with a 7 speed auto transmission. They also made it rwd using an E430 diff and axles. It took them 8 months to do this and we say it was 8 months well spent. How cool would it be to get paid to work on a project like this?
